Most sunglasses cases—often standard-issue with purchase, a generic afterthought, or a pouch too flimsy to carry fragile frames—don't do justice to the accessories they contain. For the detail-obssesed, Steve Mono's Tony Capitol collection makes a polished way to stow eyewear out of harm's way.

Founded in 2006, Steve Mono (a Spanish leather goods line) keeps the design of the case refreshingly straightforward with clean lines, subtle hardware and spare branding. Designer Gonzalo Fonseca, inspired by the "classic, easy and cool" pieces he often spots in vintage films, book and photographs, creates accessories for men but notes "women use and like to steal their men's bags."

Available in blue or red, the Tony Capital case sells from Opening Ceremony for $75.
